For a child weighing 28 pounds, what compression method is appropriate to ensure high-quality chest compressions?

For performing chest compressions on a child weighing 28 pounds, using the one-hand technique is deemed appropriate. This technique allows for effective compressions while being manageable given the child's size. The one-hand method incorporates the use of one hand to compress the chest, which is particularly useful in situations where the child is smaller or when accessing the chest is somewhat restricted, ensuring that the provider can maintain proper positioning and depth of compressions.

High-quality chest compressions require a firm, rhythmic approach that allows for proper recoil. The one-hand technique facilitates this, as the provider can maintain better control and adjust their position as necessary to ensure compressions are deep enough, at least one-third the depth of the chest, and at a rate of 100 to 120 compressions per minute. This technique also helps in minimizing fatigue for the rescuer, which is essential in an emergency when continuous and effective compressions are critical.

In contrast, other methods, such as the two-hand or encircling thumbs technique, tend to be more suitable for larger children or adults, where there is more body mass to support two-handed compressions. The interlaced fingers technique generally fits into adult resuscitation more effectively as well, where a firmer, more secure
